Hi, Yes I know I've to use the "on error" property, but the cue is to raise an error if query has a false result: for my knowledges the only way to do it is to "create or replace" a PL/pgSQL procedure that than uses a "RAISE ERROR" inside, but isn't there a more "SQL only way to do it?
thanks in advance, G

The only thing I could see here:
https://www.pgadmin.org/docs/pgadmin4/development/pgagent_jobs.html
that might work is:
"
Use the On error drop-down to specify the behavior of pgAgent if it
encounters an error while executing the step. Select from:
Fail - Stop the job if you encounter an error while processing this
step.
Success - Mark the step as completing successfully, and continue.
Ignore - Ignore the error, and continue.
"
So in the first step induce an error if the conditions are not met.
